Receiving and handling
Upon receipt, carefully inspect the trans-
fer switch for damage that may have oc-
curred during transit. If damage is evi-
dent, or there is visible indication of
rough handling, immediately file a dam-
age claim with the transportation com-
pany, and notify your local ABB sales
office.
Do not remove the shipping packaging
until ready to install the switch.

immediately, store the transfer switch in
its original package in a clean, dry loca-
tion. To prevent condensation, maintain a
uniform temperature. Store the unit in a
heated building, allowing adequate air cir-
culation and protection from dirt and
moisture. Storing the unit outdoors could
cause harmful condensation inside the
transfer switch enclosure.
